摘要： The invention relates to cinnamic acid derivatives of formula S wherein the radicals have the meaning indicated in claim 1, to a process for their preparation and their use as self assembling photoalignment agent in liquid crystal mixtures. The invention further relates to a process for the fabrication of a liquid crystal (LC) display device with homogeneous alignment by photoaligning a liquid crystal mixture with positive or negative dielectric anisotropy comprising one or more compounds of formula S and optionally a polymerizable compound, to the liquid crystal mixture comprising the self assembling photoaligning agent and optionally the polymerizable compound and to the LC display produced by said process.

摘要： Suggested are new adhesion promoters, which are particular suitable for use in displays. Its inclusion in the polymerisable LC mixture results in an excellent adhesion on substrate without colouration over time i.e. compared to amino siloxanes. The new additives have no effect on alignment of LC on the substrate while improving the adhesion.
